Abstract (en)

A signal-processing apparatus is capable of stably operating without regard to outside circumstances and miniaturizing. The signal-processing apparatus for shifting phase of a signal inputted thereto and attenuating the signal includes an input connector for inputting a signal; an output connector for outputting the signal; a rotation body to be rotated by the rotational force provided from the rotational force supplying means; a plurality of rotatable members respectively having a groove in peripheral portion, the rotatable members being coupled to peripheral portion of the rotation body so that the grooves communicate with each other; and a signal transmitting member for transmitting the inputted signal to the output connector, the signal transmitting member being located in the grooves and its both ends being respectively connected to the input and output connectors. <IMAGE>
